Method for customizing digitalized shoe trees according to a plurality of images of foot shapes

Abstract

The invention relates to a method for directly generating digitalized shoe trees by using foot shapes, solving the difficult problem of customizing shoe trees by measuring feet. The method comprises the following steps: (1) selecting shoe tree samples to form a shoe tree sample set; (2) designing gauge points, determining gauge points on each shoe tree sample and then acquiring the positions of the gauge points by using a scanner to obtain gauge point distribution models of the shoe tree samples; (3) aligning the gauge point distribution models of the samples; (4) generating statistic deformation models of the shoe trees; (5) calibrating the parameter of each camera and then acquiring a plurality of images of target foot shapes; (6) calculating the center of gravity of the foot shapes; (7) estimating the sizes of the foot shapes; (8) estimating the direction of the foot shapes; (9) changing individual vectors in the statistic deformation models of the shoe trees according to the plurality of images of the foot shapes until the projection of the models in each image is most identical with the true images of the foot shapes; and (10) outputting digitalized three-dimensional shoe tree models. The invention has the advantages of full automation, high speed and efficiency, simple use, low cost and the like.

Description

technical field [0001] The invention relates to a method for customizing digital shoe lasts from multiple images of foot shapes. Reconstruction, shoe last design, shoe and last customization and other fields. Background technique [0002] The invention relates to a method for customizing a digital shoe last according to multiple images of the foot shape, which can generate a three-dimensional digital shoe last that matches the shape of the foot, can measure the foot to determine the last, and can also be used for foot shape measurement, foot shape reconstruction, Shoe last design, shoe and last customization and other fields. [0003] Shoe last is a standardized shoemaking tool made according to a large number of foot shape statistics. It is a shoemaking mold processed according to foot shape and shoemaking requirements. It is actually a standardized foot shape. This standardized shoe last erases the individual factors of the foot shape and emphasizes the common shape of t...
